This page uses $_GET to grab an asset id and query a mysql database and return some information.
If 'id' does not match anything, no results are displayed but the page looks fine. If 'id' is null an error would occur at $id = $_GET["id"] or die(mysql_error()); When this occurs, they page layout is not displayed correctly. How do I fix this?
Bonus question: How would I get a message like "No matching results found" or something when the id does not match any id in the database or is null.
Thank you.
